4 MULTIPLE RlFFLEy-SAMPLER- Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filedlluly 20,1906. Serial No. 327,070-

To all whom, it may concern.-

Be it known that I, EVANS W. BUSKETT, a citizen of the United States, residing at Coffeyville, in the county of Montgomery and 5 State of Kansas, have invented certain new and useful Im rovements in Multiple Riffie- Samplers; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others 1 0 skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in rifi'le-samplers; and the object of the invention is to produce an apparatus of this character for securing samples of ore for assaying or other purposes; and it comprises, essentially, an inclined rack having three or more series of rifiies so arranged that a quantity of ore may be subdivided into equal partsof various predetermined quantities. For instance, a quantity of ore being deposited in one series of riffles would be subdivided so as to secure oneeighth of the quantity in a sampling-pan. In another series of riffles one-fourth of the sample may be saved. In a third series one-half of the sample may be conducted into the sam le-receptacle, &c.

T e invention comprises various details of construction, combinations, and arrangement of parts, all as will be more fully herein- 3 5 after described, shown in the accompanying drawings, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the let- 0 ters of reference marked thereon, form a part of this specification, and in which 1 Figure 1 is a perspective view of my improved rifile-sampler. Fig. 2 is a section taken upon the line 2 2 of Fig. 1

Reference now being had to the details of the drawings by letter, A designates the legs of the apparatus supporting the frame A to which the rifii-frame A is hinged, as at A, to hold the same securelyinplace. Theforward 5o legs are shorter than the rear, in order that the sampler may have an inclination of substantially forty-five degrees, whereby the ore which is deposited in the same may be readily gravitated down the inclinations and into the sample-receiving receptacle. B designates a hopper which is mounted adapted to receive the ore which is to be sub divided, so that one-eighth of the quantity may be deposited in the sample-containing receptacle or pan A D designates verticallydisposed partitions alternately arranged in the inclined partitions D the lower ends of the said partitions D being continuous with the parti tions C, which partitions D are in alinement with the longitudinal middle portion of one of the troughs or riflles of the series C. The space at the right of each partition D has an opening D adjacent thereto, whereby. as the ore which is deposited in the various rifiies O is divided into equal parts by the partitions D one-half of the ore falls through the opening D while the other half passes over the bottoms D intermediate the vertical partitions D and the inclined partitions D The ore which passes down upon the bottom of the spaces intermediate the partitions D and D is further subdivided into equal quantities by the vertical partitions D in the lower row of riflies.

It will be noted. that the vertical partitions D are disposed in such manner that they will divide the ore equally, one-half of the ore which is divided by the partitions D passing down the bottoms D into the sampling-pan beneath, while the other halves of the quantities divided by the partitions D pass through the openings D which openings alternate with the bottoms D and the ore passing through the same is directed by the hopper into the receptacle B. In a similar manner when the ore is poured into the series of rifi'les D one-half passes through pouring the ore upon the lower series F of the riffles it. will be noted that one-half of the sample is saved, while the other half is discarded and falling through the openings D is directed by the hopper into the receptacle,

It will be observed that the alternate partitions D in the series of riffles D are inclined in order to divide the space equally, and that in the third series of riffles F it is necessary to have one-fourth of the riffles upon the left and three-fourths upon the right end of the series in order to divide the space equally. Said small rifile of one-third the size of the others is used only when cutting the samples upon the third series F and does not effect the operation of the upper series of rifiies. It will be noted also that there are partitions 7L positioned between alternate troughs or rifiies in the series F, which are provided for the purpose of dividing the discarded ore from the riffle before falling into the sample pan or receptacle A Suitable Wires N extend across the front of the'rifiie-sampler and are fastened to the upper edges of the vertical and inclined walls of the riffies, thus securely bracing the same.

By the provision of the apparatus shown and described a multiple rifile-sampler is afforded whereby one-half, one-fourth, oneeighth, or any other multiple of the quantity of ore may be separated into sample-pans for assaying or other purposes.

What I claim is 1. A multiple riflie-sampler, comprising a frame set at an inclination, a series of riffies at the upper part of the frame alternating with openings, whereby the ore may be divided into equal parts, a second series of riffies beneath the first-mentioned series and adapted to equally subdivide the samples from the first series and a third series of riffles beneath the second series designated to further subdivide the samples from the sec ond series into equal parts, the alternate partitions in said second series being at inclinations and overhanging spaces intermediate the second series of riflies, as set forth.

2. A multiple riffle-sampler, comprising a frame set at an inclination, a series of riffles at the upper part of the frame alternating with openings, whereby the ore may be divided into equal parts, a second series of riffies beneath the first-mentioned series and adapted to equally subdivide the samples from the first series and a third series of I'lf:

fies beneath the second'series designated to EVAN-S W. BUSKETT.
